Excel VBA parse column, extract all substrings - excel

Question

I'm trying to parse a column that contains data in the following format in each cell -
pull: test1
or
pull: test2|pull: test3|.....
or
other: blah...
I only want a grab each "Pull: test" and place 1 in each row in a new worksheet like below, and ignore any parts of the cell that don't begin with "pull: " -
pull: test1
pull: test2
pull: test3
...
What I have so far just pulls the entire column and pastes into the same spreadsheet, I'm not sure how to separate the items in each cell into their own rows. I also can't get it to pull to a different worksheet correctly either (commented out my attempt)
Sub InStrDemo()
Dim lastrow As Long
Dim i As Integer, icount As Integer
'Sheets.Add.Name = "TEST"
lastrow = ActiveSheet.Range("A10000").End(xlUp).Row
For i = 1 To lastrow
If InStr(1, LCase(Range("E" & i)), "pull:") <> 0 Then
icount = icount + 1
'Sheets("TEST").Range("A" & icount & ":E" & icount) = Worksheets("SearchResults").Range("A" & i & ":E" & i).Value
Range("L" & icount) = Range("E" & i).Value
End If
Next i
End Sub

Option Explicit
Sub testDemo()
Dim sourceSheet as worksheet
Set sourceSheet = ActiveSheet ' would be more reliable to qualify the workbook and worksheet by name'
Dim outputSheet as worksheet
Set outputSheet = thisworkbook.worksheets.add
Dim lastRow As Long
lastrow = sourceSheet.Range("A10000").End(xlUp).Row
' I assume column E needs to be parsed'
Dim arrayOfValues() as variant
arrayOfValues = sourceSheet.range("E1:E" & lastRow)
Dim rowIndex as long
Dim columnIndex as long
Dim splitString() as string
Dim cumulativeOffset as long
Dim toJoin(0 to 1) as string
toJoin(0) = "pull: test" ' Might speed up string concatenation below'
Dim outputArray() as string
With outputsheet.range("A1") ' The first row you want to start stacking from'
For rowIndex = 1 to lastRow
' Single dimensional, 0-based array'
splitString = VBA.strings.split(vba.strings.lcase$(arrayOfValues(rowIndex,1)), "pull: test",-1, vbbinarycompare)
Redim outputArray(1 to (ubound(splitString)+1), 1 to 1)
For columnIndex = lbound(splitString) to ubound(splitString)
toJoin(1) = splitString(columnIndex)
Outputarray(columnIndex+1,1) = VBA.strings.join(toJoin, vbnullstring)
Next columnIndex
'Instead of splitting upon a delimiter, then prepending the delimiter to each array element (as is done above), you could repeatedly call instr(), use mid$() to extract the sub-string, then increase the argument passed to the "Start" parameter in instr() (effectively moving from start to end of the string) -- until instr() returns 0. Then move on to the next string in the outer loop.'
.offset(cumulativeOffset,0).resize(Ubound(outputArray, 1), 1).value2 = outputArray
cumulativeOffset = cumulativeOffset + ubound(splitString)
Next rowIndex
